An object of the invention is to provide a The tube is formed of suitable material having steam heater tube which may be attached readily, suicient rigidity to maintain the shape of the quickly, and securely to a source of steam suptube, and said material is preferably s `irally 'ply and which may be positioned quickly upon wound into the cylindrical shape of the tube. ai curling rod and securely clamped or held to The tube is composed preferably of two differthe'hair of the person receiving the wave. ent materials, the inner material I being suoli a`s 10 Another object of the invention is to provide a to absorb moisture and the outer materialv II io Isteam heater tube which is simple and economical being impervious to moisture, as, for example,

Although the closure is tight enough to or closure member for sealing the open end of prevent the leakage of condensation, it is not so 55 receive a 'fitting on the end of the steam supply pipe and is provided with an opening extending laterally from the bore in which is movably arranged a ball detent I6. The detent I6 is held normally in a position to have a portion projecting into the bore of the fitting I5 by means of a wire spring I'I engaging the detent and encircling the fitting I5 with one end anchored in the fitting.

The cap or closure member I4 is provided with a slot I8 extending longitudinally inwardly of the member from its open slightly ared end as clearly shown in Fig. 2. In order to maintain the cap or closure member I4 securely on the tube and to prevent its accidental displacement therefrom, the member is provided just inwardly of its open end with one or more barbs or prongs I9 extending inwardly of the member and preferably struck from the material of the member and adapted to dig into the material of the tube.

'Ifhe steam supply pipe is shown at 2U and has a tting 2I on its end adapted to pass into the fitting I5 of the cap or closure member with a sliding but tight fit, which fitting 2l has a notch 22 into which snaps the ball detent I'I to hold the fitting 2I securely in the cap or closure member.

It will be understood that a plurality of the tubes are used when Waving a customers hair, but since each tube is applied in an identical manner, only the application of one tube need be explained.

The hair 23 is wound upon a curling rod 24 in a manner well understood, after which the rod with the wound hair thereon is slipped into the tube with the open end of the tube adjacent the customers head. The cap or closure member I4 is then positioned upon the open end of the tube with the strand of hair passing through the slot I8. The open end' of the tube is thus sealed while the hair is clamped between the tube and the cap or closure member. The steam` supply pipe 20 is then connected to the tube by inserting the fitting 2| into the bore of the fitting I5 carried by the cap I4 until the detent II snaps into the notch 22 of the fitting ZI.

Although a preferred embodiment of the invention has been illustrated and described herein,

it will be understood that the invention is susceptible of various modifications and adaptations within the scope of the appended claims.

- Having thus described my invention, I claim:

1. A hair waving heater of the steam type comprising a tube open at one end and closed at the other end by a pressed flattened portion of the tube material, and a removable cap closing the open end of the tube and having means for attaching a steam supply pipe thereto in communication with the interior of the tube.

2. A hair waving heater of the steam type comprising a tube open at one end and having the material of the tube at its opposite end deformed and pressed together into adherent relationship to form a closure for said end of the tube.

3. A hair waving heater of the steam type comprising a tube formed exteriorly of moisture impervious material and interiorly of moisture absorbent material, said tube being open at one end and having the materials of the tube at its opposite end deformed and pressed together into adherent relationship to form a closure for said end of the tube.

4. A hair waving heater of the steam type comprising superimposed strips of water-impervious and moisture absorbent materials wound to form a tube, said tube being open at one end and having the materials of the tube at its opposite end deformed and pressed together into adherent relationship to form a closure for said end of theV tube.

5. A hair waving heater of the steam type comprising a tube open at one end and having the material or the tube at its opposite end deformed and pressed flat together into adherent relation- K ship to: form a closure for said end of the tube;

6. A hair waving heater of the steam type comprising a tube open at one end and having the material of the tube at its opposite end deformed and pressed flat together into adherent relationship to form a closure for said end of the tube, said closure being disposed angularly with respect to the longitudinal center line of the tube.

7. A hair waving heater of the steam type comprising superimposed strips of water-impervious and moisture-absorbent materials wound to form a tube, said tube being open at one end and having the materials at its opposite end deformed and pressed flat together into adherent relationship to form a closure for said end of the tube, said closure being disposed angularly with respect to the longitudinal center line of the tube.
